Semtech (Camarillo, CA) has introduced the SX1272, the first product in a new long-range RFIC platform that boosts the transmission range of the devices to up to 15 kilometers (km). This device integrates Semtech’s new LoRa (long range) modulation technology to enable drastic range improvements over alternative modulation methods. The SX1272, utilizing LoRa operating under the same conditions and regulatory limits, can transmit more than 15 km. Additional range eliminates need for repeaters, significantly simplifying the system design and lowering the total cost of deployment. The range extension provided by LoRa also makes the device ideal for emerging smart city, Internet of things (IOT) and machine-to-machine (M2M) applications. Features include:

  • Receiver sensitivity up to -137 dBm utilizing a low-cost crystal. 
  • 25 dB improvement over FSK devices for rejecting in-band interfering signals. 
  • Low current consumption.
  • Bit rates up to 300 kbps.
  • 72 dB adjacent channel selectivity.
  • 66 dB image attenuation.
